- the PDT 100 may be also designed to attach fixed, movable or removable features or accessories to facilitate the usage of the keyboard 130, enhance visibility of the display screen 120, or to enable scanning objects when resting on a surface.
- the PDT 100 provides a superior form factor for a mobile computer that may provide one or more of the following advantages:
- FIG. 6 An embodiment of an internal electronics package 161 is diagrammatically illustrated in Fig. 6 , which includes left and right cameras 170, 172 and a data reader comprising a scan engine 162, separate (optional) illumination source 180, and a good read indicator 189 (shown as the "Green Spot" indicator).
- the components of the electronics package 161 are disposed within the central housing portion 160.
- Fig. 6 also illustrates positions of the batteries 142, 152 on opposite sides of the central housing portion 160.
- the data reader comprises a scan engine 162 comprising internal electronics and a reading mechanism such as an imager 163 (typically comprising a CCD or CMOS sensor and lens element) for reading optical codes placed in the read region 20 of the PDT 100.
- a scan engine 162 may comprise some other reading mechanism such as a laser scanner or other suitable optical code or item reading mechanism.
- the scan engine 162 may comprise some other data reader such as an RFID reader, or a combined RFID/optical code reader.
- the scan engine 162 may further comprise its own illumination source, such as light emitting diodes (LEDs) 164, 165 which produce an illumination field 169 (as shown in Figs. 7-8 ).
- LEDs light emitting diodes
- one or more of the LEDs 164, 165 may comprise aiming illumination to assist the user in aiming the data reader onto an object/optical code.
- a separate (optional) illumination source 180 for example comprised of LEDs 182, 184, 186, 188, may be provided to produce a secondary (or primary) illumination field 181 to illuminate the read region 20.
- the electronics package 161 may include the good indicator mechanism 189 in the form of a light source, for example a light emitting diode (LED) with or without an optional focusing lens.
- the indicator light source (which will be hereinafter referred to as the indicator LED) is preferably independently powered with respect to any other LEDs (or laser diodes) used by the data reader that projects a spot of light, visible to the user, on or in the vicinity of the optical code signifying a successful read by the data reader, thereby signifying a "good read.” It is desirable that the indicator LED be sufficiently luminous for generating a luminous figure (e.g., a round spot of light) on the object being read that is clearly visible in a well-lighted environment.
- a luminous figure e.g., a round spot of light
- conventional SMD package LEDs can be used in conjunction with a collimating or focusing lens and possibly a suitable aperture to shape the beam of light emitted by the LED.
- the indicator LED of the good read indicator 189 may emit light of any suitable color, but green light is preferably used.
- a green light provides positive indications or indications of a good operation, as for traffic lights or the indication LEDs on electronic equipment, and in addition, the light of the illuminator for acquiring the code is usually red; thus, green light allows highlighting the difference with respect to the light projected for illuminating the optical code for its acquisition. Further, the good read indicator is advantageous for noisy environments where the standard beep of a positive read cannot be heard.
- the large landscape form factor of the PDT 100 also permits the inclusion of the left and right cameras 170, 172 that may acquire 3D data using stereoscopy techniques (e.g., to acquire volumetric information on a potentially bulky 3D package/parcel/item where a large 3D field of view is needed), and one or more of these cameras may be employed as thermocameras (thermal imaging cameras) or distance measuring equipment (e.g., measuring 3D objects). Alternately, the cameras 170, 172 may be used as additional data reading imagers. Such spacing of the left and right cameras 170, 172 used as data readers may provide advantages for alternately reading optical codes from different angles which may useful for reading optical codes on reflective surfaces that otherwise are unreadable due to light saturation from reflected illumination.
- Fig. 9 illustrates the PDT 100 of the prior embodiment further indicating an accessory mating area 167 on the underside of the main housing 105 between the battery housing sections 140, 150 and behind the central housing portion 160.
- the accessory mating area 167 may be used to attach or otherwise mate accessory components to the main housing 105.
- Possible accessories that may be attached may include a handle (such as the central handle 190 illustrated in Figs. 11-13 ), a mounting area such as for mounting on a docking station, magnetic stripe readers, RFID readers, vehicular docks or mounting brackets on a vehicle such as a scooter or a bicycle, a holster or lanyard mount, an orientable stand (e.g., for holding the PDT to enable hands-free scanning), or other suitable accessory.
- a handle such as the central handle 190 illustrated in Figs. 11-13
- a mounting area such as for mounting on a docking station, magnetic stripe readers, RFID readers, vehicular docks or mounting brackets on a vehicle such as a scooter
- FIG-13 illustrate one type of mating mechanism for the accessory mating area 167 comprised of a dovetail mount 166, as best shown in Figs. 9, 10 and 13 .
- the female dovetail 166 in the main housing 105 mates with a male dovetail 192 of the handle 190 as illustrated in Fig. 13 .

- An embodiment of an
internal electronics package 161 is diagrammatically illustrated inFig. 6 , which includes left andright cameras scan engine 162, separate (optional)illumination source 180, and a good read indicator 189 (shown as the "Green Spot" indicator). The components of theelectronics package 161 are disposed within thecentral housing portion 160.Fig. 6 also illustrates positions of thebatteries central housing portion 160. - The data reader comprises a
scan engine 162 comprising internal electronics and a reading mechanism such as an imager 163 (typically comprising a CCD or CMOS sensor and lens element) for reading optical codes placed in the readregion 20 of thePDT 100. Alternately thescan engine 162 may comprise some other reading mechanism such as a laser scanner or other suitable optical code or item reading mechanism. Still alternately, thescan engine 162 may comprise some other data reader such as an RFID reader, or a combined RFID/optical code reader. - Though an imaging reader may read optical codes using only ambient light, the
scan engine 162 may further comprise its own illumination source, such as light emitting diodes (LEDs) 164, 165 which produce an illumination field 169 (as shown inFigs. 7-8 ). Alternately, one or more of theLEDs LEDs illumination source 180, for example comprised ofLEDs illumination field 181 to illuminate the readregion 20. - In embodiments wherein the
scan engine 162 comprises an optical code reader, theelectronics package 161 may include thegood indicator mechanism 189 in the form of a light source, for example a light emitting diode (LED) with or without an optional focusing lens. The indicator light source (which will be hereinafter referred to as the indicator LED) is preferably independently powered with respect to any other LEDs (or laser diodes) used by the data reader that projects a spot of light, visible to the user, on or in the vicinity of the optical code signifying a successful read by the data reader, thereby signifying a "good read." It is desirable that the indicator LED be sufficiently luminous for generating a luminous figure (e.g., a round spot of light) on the object being read that is clearly visible in a well-lighted environment. A suitable green light LED may comprise an epoxy resin package having a diameter of 5 mm, peak wavelength of w=524 nm and emission angle of 15°, such LEDs being available from various manufacturers. Alternatively, conventional SMD package LEDs can be used in conjunction with a collimating or focusing lens and possibly a suitable aperture to shape the beam of light emitted by the LED. The indicator LED of thegood read indicator 189 may emit light of any suitable color, but green light is preferably used. A green light provides positive indications or indications of a good operation, as for traffic lights or the indication LEDs on electronic equipment, and in addition, the light of the illuminator for acquiring the code is usually red; thus, green light allows highlighting the difference with respect to the light projected for illuminating the optical code for its acquisition. Further, the good read indicator is advantageous for noisy environments where the standard beep of a positive read cannot be heard. - The large landscape form factor of the
PDT 100 also permits the inclusion of the left andright cameras cameras right cameras -
